/mcpDescription Interfaces You can configure the ciphers for all supported TLS interfaces of Cisco Unity Connection. Example: SIP, SCCP, HTTPS, Jetty, SMTP, LDAP and IMAP inerfaces. All TLS You can configure the ciphers for all Cisco Tomcat interfaces of Cisco Unity Connection. HTTPS TLS You can configure the ciphers for SIP interfaces of Cisco Unity Connection. Example: Telephony User Interface to support secure SIP call in Unity Connection. Cipher configuration for SIP interface is not supported for unrestricted version of Cisco Unity Connection. Note SIP TLS SSH Interfaces You can configure ciphers and algorithm for the SSH interfaces mentioned below. Description Interfaces You can configure the cipher for SSH interfaces of Cisco Unity Connection. SSH Ciphers You can configure the SSH Key Exchange algorithm for SSH interfaces of Cisco Unity Connection. SSH Key Exchange You can configure the SSH MAC algorithm for SSH interfaces of Cisco Unity Connection. SSH MAC For information on recommended ciphers, see the "Cipher Management" section in the Security Guide for Cisco Unified Communications Manager at https://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html. Configuring Cipher String To configure the cipher string for TLS and SSH interfaces, do the following procedure: Step 1 Navigate to Security > Cipher Management. The Cipher Management page appears. Step 2 On the Cipher Management page, enter the cipher string in Cipher String field for All TLS, HTTPS TLS and SIP TLS interfaces. The cipher string configured either for HTTPS TLS or SIP TLS interface overrides the cipher string configured in ALL TLS field. Note The ciphers configured on the Cipher Management page will override the cipher configuration of Edit General Configuration page. Hence it is recommended to use Cipher Management page for configuring the ciphers for TLS and HTTPS interfaces. Note Step 3 Enter the cipher string in Cipher String field for SSH Ciphers. Step 4 Enter the algorithm string in Algorithm String field to configure the key algorithm for SSH Key Exchange.
